Hair clipper



March 1 J. w. McDANlEL HAIR CLIPPER Filed Dec. 20, 1953 Inventor 9 :72:21 Jana M Attorney Patented Mar. 12 1935 UNITED: STATES PATENT OFFICE 1 Claim.

The present invention relates to new and useful improvements in hair clippers of the type in widespread use at present by barbers and has for its primary object to provide, in a manner as hereinafter set forth, a hair clipper comprising a base plate having rollers journaled thereon to facilitate the movement of the clippers over the head while at the same time permitting the hair to be more evenly out.

Another very important object of the invention is to provide a hair clipper of the aforementioned character embodying novel means for mounting the rollers beneath the base plate.

Other objects of the invention are to provide a hair clipper which will be simple in construction, strong, durable, highly efficient and reliable in use and which may be manufactured at low cost.

All of the foregoing and still further object and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in side elevation of a hair clipper constructed in accordance with the present invention.

Figure 2 is a view in transverse section through the base plate taken substantially on the line 2-2 of Figure 3.

Figure 3 is a View in bottom plan of the base plate.

Figure 4. is a fragmentary view in transverse section, taken substantially on the line 44 of Figure 1.

Figure 5 is a fragmentary view in transverse section, taken substantially on the line 5-5 of Figure 3.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a casing l the rear portion of which is formed to provide a handle 2, as usual.

As will be understood, the casing 1 houses the usual electrically driven mechanism which actuates the reciprocating cutter 3 of the clipper.

The reciprocating cutter 3 coacts with a stationary toothed base plate which is designated generally by the reference numeral 4. The base plate a is rigidly secured on the forward end portion of the casing l in the usual manner, as at 5.

In its lower side, the base plate 4 has formed transversely therein a pair of spaced channels 6. Removably secured, as by screws '7, on the longitudinal edges of the plate 4 are side bars 8 hav ing tongues 9 on their inner sides engaged in grooves 10 which are provided therefor in said plate 4.

The channels 6 in the plate 4 are for the ree ception of rollers 11 having trunnions 12 on their ends which are journaled in apertured ears 13 which depend fromthe side bars 8.

It will thus be seen that the transverse rollers 11 are mounted to project below the lower side of the base plate 4 for rolling contact with the head of the person whose hair is being cut. It will further be seen that a construction and arrangement have been provided whereby the assembly of the base plate with its rollers, etc. is materially facilitated. As is believed to be apparent, a clipper constructed in accordance with this invention may be moved over the head with comparative ease and assures even cutting of the hair.

It is believed that the many advantages of a hair clipper constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of con struction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

In a hair-clipper, a base plate having spaced transversely extending channels in its lower face and grooves in its side edges, a pair of bars of the same width as the thickness of the plate, said bars contacting the side edges of the plate, screws for fastening said bars to the plate, a rib on the inner face of each bar for entering the grooves, each bar having perforated depending ears thereon and rollers having portions located in the channels and having trunnions at their ends entering the perforations in the ears.
